Pregnancy in patients after homograft cardiac valve replacement.

Thirteen pregnancies in ten patients with homograft cardiac valves resulted in 11 healthy infants, one spontaneous abortion, one elective termination of pregnancy, and the stillbirth of one member of a twin pregnancy. Two forceps deliveries and three cesarean sections were performed and routine antibiotic prophylaxis at the time of delivery was utilized to prevent infective endocarditis in all patients. No hemorrhagic or teratogenic complications were observed, and this was considered directly related to the fact that anticoagulant therapy was rendered unnecessary with the homograft valve--a distinct advantage. A more permissive policy of allowing pregnancy in young women with homograft cardiac valves is suggested by the satisfactory outcome of the pregnancies reported here.

Myomectomy in infertile Jamaican women.

One hundred nineteen Jamaican women who underwent myomectomy from 1964 to 1969 were followed up for 5 to 9 years. Infertility was the most common presenting complaint. Preoperative hysterosalpingograms were performed on 61 patients and were abnormal for the majority of these patients. Surgery revealed submucous fibroids in 41 patients and pelvic inflammatory disease in 51 patients. The pregnancy rate following myomectomy was 18.5%, but successful outcomes occurred in only 9.2% of the cases. Pregnancy was unsuccessful for all patients who underwent both myomectomy and tuboplasty. Twenty-three patients had a recurrence of myoma, and 13 of these underwent subsequent hysterectomy.

Cord and maternal serum meperidine concentrations and clinical status of the infant.

The possible relationship between the use of meperidine during labor and fetal or neonatal distress was investigated by correlating clinical parameters with maternal and cord serum concentrations of meperidine. The serum concentration of meperidine was determined by a radioimmunoassay which is 100-fold more sensitive than previously employed techniques and can detect as little as 0.02 nmol meperidine/ml. The incidence of fetal or neonatal depression following meperidine administration was higher (6 of 17 infants) than in a control group but no correlation between suppression and the route of meperidine administration or the serum meperidine concentrations at the time of delivery was found.

The effect of epidural anesthesia on uterine activity and blood pressure.

Because of the unresolved controversy regarding the effect of epidural anesthesia upon uterine contractility, it was decided to study its effect on a small number of patients. Intrauterine and intra-arterial continuous pressure, continuous fetal heart rate, and maternal heart rate recordings were obtained from at least 20 minutes before administration of the epidural anesthic until complete dilatation in these patients. Nineteen patients were in spontaneous labor, and 18 had labor stimulated with oxytocin. Plain lidocaine, 1 or 1.5%, was used in 12 patients (30 observations), and lidocaine with epinephrine, 1:200,000 was used in 26 patients (51 observations). Uterine contractions were calculated in Montevideo units for 60 minutes following the epidural anesthetic. The changes, if any, were compared in both groups. There was a significant decrease in uterine activity when epinephrine was added to the anesthetic solution, mainly a lessening of intensity. There were comparable decreases in systolic/diastolic blood pressure in both groups and compensatory tachycardia. In one case, severe hypertension was observed following administration of lidocaine epinephrine. It was concluded that the addition of epinephrine to the anesthetic solution predictably produces diminution of uterine activity, and it does not give "cardiovascular support" to the laboring patient.
